1 Effects of protracted nicotine exposure and withdrawal on the expression and phosphorylation of the CREB gene transcription factor in rat brain. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
2 Addiction to nicotine may result in molecular adaptations in the neurocircuitry of specific brain structures via changes in the cyclic AMP-responsive element binding protein (CREB)-dependent gene transcription program. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
3 Addiction to nicotine may result in molecular adaptations in the neurocircuitry of specific brain structures via changes in the cyclic AMP-responsive element binding protein (CREB)-dependent gene transcription program. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
4 On the other hand, decreases in the expression of CREB protein and phosphorylation of CREB occur in the cingulate gyrus, and in the parietal and the piriform but not in the frontal cortex during nicotine withdrawal (18 h) after nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
5 On the other hand, decreases in the expression of CREB protein and phosphorylation of CREB occur in the cingulate gyrus, and in the parietal and the piriform but not in the frontal cortex during nicotine withdrawal (18 h) after nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
6 On the other hand, decreases in the expression of CREB protein and phosphorylation of CREB occur in the cingulate gyrus, and in the parietal and the piriform but not in the frontal cortex during nicotine withdrawal (18 h) after nicotine exposure.

Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
8 It was also observed that CREB and p-CREB protein levels were significantly decreased in the medial and basolateral, but not in the central amygdala during nicotine withdrawal (18 h) after chronic nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
9 It was also observed that CREB and p-CREB protein levels were significantly decreased in the medial and basolateral, but not in the central amygdala during nicotine withdrawal (18 h) after chronic nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
10 It was also observed that CREB and p-CREB protein levels were significantly decreased in the medial and basolateral, but not in the central amygdala during nicotine withdrawal (18 h) after chronic nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
11 It was also observed that CREB and p-CREB protein levels were significantly decreased in the medial and basolateral, but not in the central amygdala during nicotine withdrawal (18 h) after chronic nicotine exposure. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
12 These results provide the first evidence that decreased CREB activity and/or expression in specific cortical and amygdaloid brain structures may be involved in the underlying molecular mechanisms of nicotine dependence. Nicotine cAMP responsive element binding protein 1 Rattus norvegicus
